I am looking to purchase a new rifle. The only rifle that I have is a old 338 that was given to me when my grandfather passed away. It is blued and walnut Winchester Model 70. I love that gun, but on wet hunts it rusts way to easily. I still will use this gun for big bears and such, but would like something for everything else. Black bear, moose, caribou, deer, etc. I am sold on the Tikka, but having a hard time with the caliber choice. I will be both reloading for it and using factory ammo. I also have 4 boys and would like something that they could shoot when they get older. Any and all suggestions please.
